ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 298,323, dated May 6, 1884.

Application filed January 4, 1884. (No model.) 4

To all 1072 0772, it may concern:

Be it known that I, YVI'LLIAM O. VANNE- MAN, a citizen of the United States, residing at Richmond, in the county of \Vayne and State of Indiana, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to that class of rollerskates in common use for parlor and rink skating.

My invention consists in the novel construction of the trucks used and in the fewer number of pieces required.

In the drawings which accompany this specification, forming part of the same, Figure l is a perspective view of the hanger and truck frame and axle and bed-plate. Fig. 2 is alongitudinal vertical section of the hanger and truck frames, showing the spring in position; also the bed-plate. Fig. 3 is a perspective View of the hanger-frame. Fig. 4 is a vertical crosssection of firetruck-frame. Fig. 5 is a front elevation of the rubber spring. Fig. 6 is a perspective of the front end of the hangerframe and bed-plate, showing another form of connecting the same. Fig. 7 is an elevation of the truck, truck-frame, and spring when the spring is thrown sidewise by the action of the hanger-frame; also showing the form of the washer used to retain the wheel upon the axle and the manner of their use. Fig. 8 is a perspective view of the bed-plate.

In Fig. 1, a represents the hanger-frame, in which a is the top surface, to which is attached the foot-piece, and which is provided with screw-holes admitting screws to secure the same.

Depending from the surface a are lugs or projections, forming the ends of the hangerframe A A, as shown in Fig. 3. The projection A is furnished with a vertical slot or opening, g, which receives the pivot h of the trucloi'ranie c. (Seen also in Fig. 2.) The pro j ection A has a similar slot or opening, 9, which is closed at its lower end by a horizontal triangular cross-bar, f, rigidly attached to the lower ends of the projection A. The edges of the cross-barf are furnished with V-shaped notches outside of its point of contact with the projection A, which receive and support the ends 0 c of the bed-plate b. The ends 6 e of the bed-plate b are recessed to fit the notches 7c 7c of the cross-bar f.

i, Fig. 1, is a temper-screw passing through an opening in the end of the bed-plate b at p, and engaging in a screw-thread in the projection A of the hanger a, as seen in Fig. 2.

d, Fig. 1, is a rectangular rubber spring resting upon the bed-plate b, and pressing against the top bar of the truck-frame 0, provided with a vertical. slot, at, Fig. 5. The lower portions of the truck-frame c are provided with holes to receive the axle Z. The truckframe 0 is provided with pivots h h, which have their bearings in the slots g g in the hanger-frame a, and upon which the hangerframe a and the foot-piece to which it is attached are permitted an oscillating motion by the action of the operator. The bed-plate b, Fig. 8, is constructed of a horizontal bar, I), having an upward-projecting rib, a, (shown in Fig. 4,) a lateral opening, 0, and loop 1) at one end of the bar, and semicircular jaws c 6, provided with notches k at the opposite end, each end being elevated above the bar I), the jaws c 6 having their bearing in the horizontal cross-barf, while the opposite end is supported by the head of the temper-screw 'i, by the action of which screw it is permitted a vertical 1notion,increasing or diminishing the pressure upon the spring (Z, which rests upon it,

and which is held in place by the rib n being inserted in the slot 00, Figs. 4 and 5.

In Fig. 7, Z represents the axle, w w the wheels and q the washer; r, the liuch-pin. s is a raised projection on the face of the washer q, the projection being highest in the centra1 portion, where the axle protrudes, at which place it is cut away. to allow a vertical linchpin to be inserted.

In Fig. 6 the front end, A, of the hanging frame is provided with curved arms 2 z, and the end of the bed-plate has a rod, m, secured horizontally between the jaws c e, which ,when placed in the curved arms a 2, produces another form of support for that end of the bedplate in which it isconveniently hinged. When the truck-frame is placed in position, with the jaws e e resting upon the crossbar f, the screw 2' is inserted in the loop 1), and screwed into its thread in the projection A, the head of the screw '1' resting against the under surface of the loop 1;, and thus raising that end of the bed-plate. The spring (I, being attached, as shown, to the upper surface of the bed-plate, is brought in contact with the under surface of the cross-bar which forms the top of the truck-frame 0, and as the screwi is turned home the pressure on the spring is increased as may be required.

It will be seen that .the hanger-frame a, the truek-frame c, and the bed-plate can be readily detached and disconnected by removing the temper-screw i, and that when these parts are in working position more or less density can be imparted to the spring (2 by means of the temper-screw i.

I am aware that it is not new to combine a pressure-plate with the roller-support, said pressure-plate being pivoted at one end, and adjustable at the other end by an adjustingscrew, and which I do not claim.

Having thus fully described my said inveir tion, what I claim as new, and desire to secure by Letters Patent, is-

1. In aroller-skate, the hanger-frame provided with pendent lugs at opposite ends, with a space between the lugs to receive a truck-frame, said lugs beingslotted vertically to receive the axles of the roller-supporting truck, substantially as described.

2. In a roller-skate, the bed-plate formed at one end with the forked arm, at the opposite end with the openings 0 and p, and between the two ends with the bar I), provided with the longitudinal rib a, substantially as described.

3. The combination of the hanger-frame provided with pendent lugs slotted vertically, and having at the end a support for a bedplate, a trucleframe adapted to have an axle connected therewith, and provided with pivots having their bearings in said vertical slots, and a bed -plate connected with said hangerframe below'the pivots of said tl11Gk-f1'fllll6, substantially as described.

4. The combination of the hanger-frame, the truck-frame having a laterally-yielding connection therewith, a bed-plate below said truck-frame, and a spring-cushion between said bed-plate and truck-frame to restore said truck-frame to its normal position when relieved from strain, substantially as described.

5. The combination of the hanger-frame, the truck-frame having a laterally-yielding connection therewith, a bed-plate below said truck-frame, a spring-cushion between said bed-plate and truck-frame, and means for ad justing said bed-plate to tighten or loosen the connection between the parts, substantially as described.

6. The combination of the hanger -fra1ne provided with pendent lugs slotted vertically, and having at the end a support for a truckframe, a truck-frame provided with journals having their bearings in said slotted lugs, a bed-plate connected with the hanger-frame below the bearings of the truck-frame, aspringcushion interposed between said trueleframe and bed-plate, and a screw for tightening the connection between said parts, substantially as described.

7. In a roller-skate, the combination, with the wheel and axle, of the washer q, provided with the projection on its face, and a linchpin to the axle to one side of the projection, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
